Shank Button for a Hat and Cap Producer in Hong Kong
A Hat and Cap Producer approached us with a shank button requirement for the Hong Kong market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- A trim that passed sampling but failed in-line because it was never cycle tested
- MOQ that was quoted per colourway rather than per style
- An interlining that bubbled after the first press
What we specified
| Item | Shank Button |
|---|---|
| Client type | A Hat and Cap Producer |
| Market | Hong Kong |
| Order volume | 10,000 pieces across 4 specifications |
| Base material | Aluminium |
| Standard size | 50 mm Width |
| Finish | Silicone Wash Finish |
| Sampling rounds | 4 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | CPSIA |
How it was resolved
- We rebuilt the specification around Aluminium and locked the tolerance before bulk.
- The finish was moved to Chrome Plating after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
Result
- 10,000 pieces delivered inside the 5-week window.
- Unit cost held within 2.0% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
